This invention relatesto apparatus useful in drying, i. e. iinishingteXtile manufactures such as hosiery, and more particularly to drying apparatus of the type characterized by a multiplicity of electrically heated profile forms over which the articles are individually stretched and thus shaped as they undergo drying. y 1 Y In connection with apparatus of the specific kind referred to, I aim to enable operation of the several forms at different heats suitable to drying articles of different thicknesses and Weights; and to securethe advantagesof simplified construction and arrangement Yas 1 regards the controls involved and the forms,

to the end of facilitating wiring initially, as well as operation and maintenance of the apparatus in use. Y,

Gther objects and attendant advantages of this invention will appear from the detailed description which follows of the typical embodiment shown in the attached drawings, whereof Fig. I is a frontal perspective view of my improved apparatus equipped with forms suitable for drying hosiery.

Fig. II is a fragmentary perspective view of one end of the apparatus, on a somewhat largerV scale, with certain parts removed to eXpose important details; and,

Fig. III is a wiring diagram showing the electrical equipment and connections Vby which the current to the several drying forms is controlled.

As depicted in Figs. I and II, the drying apparatus of my invention comprises a table with a frame constructed, in the present instance, from structural iron Vwith end stand ards 10, 11, and an intermediate standard 12,

joined at their upper ends by longitudinale '13, with a top 14 of wood or the like mounted thereon. Extending vthe length of the table top 14 from one end frame 10 to the other 11 is a tubular rod 15 which serves to support a series of profile drying forms 16 of a conventional type heated by electric resist-l ance coils (not illustrated) at their interiors.v

As shown, these forms 16 have basal portions l 17 with depending stems 18 which are journaled, with capacity for limited swiveling motion, in twin bearing lugs of brackets 19 secured'lto .the tubularV supporting rod 15 aforesaid. By virtue of such mounting, the

i forms 16 can be turned about as required for convenience of inspecting the stockings forVVA imperfections, sponging them, etc. Medi ally of its length, the table top 14 has an-elongated opening 20 that affords access to an underlying receptacle 21 for wet hose which are to Y be dried. The plane ends of the table top 14 'beyond the opening 2O are, on the other'hand, reserved for the finished hosiery taken from the forms 16.V

The electric equipment of the apparatus includes an auto-transformer 22 which is secured'to the .standard 11 at the right hand PHILADELPHIA, EENNSYLVANIA, A

end of thefapparatus; a device 23 for controlling the transformer 22 as hereinafter noted; Y

a main switch 24; and fuses protected within a boX 25 g' said control device, main switch a'ndfuse box being. mounted on theleft hand end standard 10 of the table.V For. convenience of circuit arrangement, the forms 16 are in the present instance 'divided into two serial groupspof siX each; and two separate conduits 26, 27 are provided for the'condud tors carrying current from the fuse box 25 to the forms 16 of the respective groups. As shown, the conduit'26 vextends half the length ofthe table and serves the first group of the lforms.16;rwhile the conduit 27 is substantially co-eXtensivef with said table and serves the secondgroupof the forms 16. VAt properly spacedintervals, the conduits 26, 27 `are provided with outlets 28 for conductor cords l29 by which the current is directly supplied to the severalforms 16. From Fig; I'it is to vbe observed thatthe conduits "26, 27 have downward branches 26a, 27 a which terminate at the back of the fusebox Y25. -The trans'- former 22 andthe control device 23 areelectrically coordinated, as will also be explained presently, byl conductors extending through .the tubular rod'15 that'supports the drying' forms 16.

- With reference now to the wiring diagram of Fig.` III, the transformer '22 isv conventionally represented asv being ofthe auto type with Vtaps extending at spaced intervals from its `conto-individual terminals 30, and

V'thecoil end leadsextending likewise to sepa# 'ille f fi rate terminals 31, 32. The control device 23 has, in the present instance, the form of a point switch with an arcuate series of button contacts including live7 points 33 all adapted to be overtravelled by control handle 34. Conductors 35 coordinating the several tap terminals 30 of the auto-transformer 22 and the points 33 of the control switch 23, together with conductors 36, 37 coordinating the terminals 38, 39 of the main switch 24 with the coil end terminals 31,32 of said transformer, pass as previously stated, through the tubular rod 15, Which, in the diagrammatic illustration of Fig. llLis conventionally represented above the forms 16. The fuses employed for individual protection of the forms 16 are mounted in pairs on blocks 40 Within the fuse box 25, and, as shovvn, are connected in parallel through leads 41, 42 and branches 43, 44 with the terminal 39 of the main rswitch V24 and the fulcrnm of the point switch `handle 34, respectively. The conductors 45 that carry the current to the .several forms 16 of the tivo groups are shown as entering the open branch ends 26a, 27a ot the conduits 26, 27, their extension in said conduits having been omitted from the diagram in view of the obviousness of the connections.

Segregation of all the electric controls, i. e. the pointsivitch 34 and the main switch 24 as Well as the fuse box 25 at one end l() of the table top 14 as herein shown and described, aside from facilitating making of the electric connections, renders operation of the apparatus extremely easy and convenient. The subdivision of the forms 16 into groups vvithv separate conduits 26, 27 for the supply con-k ductors 29 also contributes toward facilitating Wiring with attendant minimization of labor costs in setting up the apparatus initially. Y

Having thus described my invention, l claim: s

1. In apparatus for drying stockings and the like, a table comprising end trames and a top; a series of electrically heated forms supported above the table top by means of a tubular bar with brackets at intervals affording a twin bearing for said forms; and electric equipment including a main switch, a transformer, a device controlling supply of current to enable varying of the'heating ef- .tect in the forms and a box housing fuses -for protection oi, the forms, said-main switch, control device and jruse box being mounted on one end frame of the table and the transformer on the other; and separate conduits extending longitudinally beneath the table top for conductors coordinating the electric devices at opposite ends of the table, and for conductors carrying current by Way of outlets with flexible connection to the several Jorms. 2. ln apparatus :tor drying stockings and the like.a table comprising end frames and a top, a tubular bar extending between the table ends With bearing brackets at intervals supporting a series of electrically heated forms, said forms being journaled in the brackets with capacity for limited svviveling movement; and electric equipment including a transformer mounted on one of the end frames, a device for controlling the transformer to vary the heating effect in the forms mountedvon the other frame end, and circuit conductors extending through the tubular bar aforesaid to coordinate the transformer and the control device.
